Uninstall os on dual boot

I have a dual boot system with 2 installs of win7 one is onthe C: partition the other is L: which is on the same drive as the first, Iwant to uninstall the one designated C: both are active as far as I can tell, can I just go to disk managementand delete it or is there a better way? Will the remaining partition revert to C:? A screenshot is included. I would appreciateany input on this, Bob

Your boot files are currently in the C: partition, and as Mike says, deleting it will stop your system from booting. But the boot files depend on an Active partition, which is C: right now. So even EasyBCD will not move the boot files as long as your setup is the same.

Making the other partition active, will allow a Startup Repair (run 3 times) to move the boot files to it, if you wanted to delete the entire partition. You do have some options as to how to configure your partitions, but make sure you have one partition designated as active before you try to reconfigure your boot.

As far as the L: question, since it appears your screen shot shows you as being booted into that partition, I will assume it will stay L: since it should have changed to C: when it became the OS (boot) partition.
